Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label Phase 1b dose-escalation study to assess the safety, tolerability, and PK of vantictumab when combined with paclitaxel.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Once the maximum tolerated dose (MTD) or maximum administered dose (MAD) has been determined, up to 10 patients may be enrolled in the cohort-expansion phase to better characterize the safety, tolerability and PK of vantictumab combined with paclitaxel. Up to approximately 34 patients may be enrolled into the study.
